resetear/fra To all whom t may concern.'

yBe itV known.' that I, JAMES NEWELL GRAVES, a citizen of the United States, residing atSan Saba, in the county ofSan Saba, State of TeXas, have invented a new and useful Boll-feevil Destroyer; and I do hereby declare the followingto be' a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to an improved boll weevil or other insect destroyeigland an object of the invention is to provide a suitable receptacle `,for cqntaining a suitable poisonous solution,into which the insects are drawn by means of a suitable fan.

A further object of the invention is to provide a rocking shaft on which a pair of agitators are mounted, in combination with means receiving power from the supporting wheels of the frame of the 'machine for oscillating said agitators.

In practical fields, the ydetails of construcg tion may necessitate alterationsgfalling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure l is a plan View of a destroyer constructed in accordance with the invention.

Fig. 2 is a sectional view on line 22 of Fig. 1.

Fig. 3 is a transverse sectional view on line 3-3 of Fig. 1.

Fig. 4 is a sectional view on line 4-4 of Fig. 1. c

Referring more especially to the drawings, 1 designates a tongue to which a frame 2, is secured. This frame 2 comprises the bars 3, which are angular in plan view and have their parts 4 secured by bolts 5 to the tongue. The rear ends of the bars have sleeves 6, which are secured on the upright portions 7' of the U-shaped axle 8, by means of the set bolts 9. The. upright portions 7 of said axle at their lower parts, terminate in the spindles 9a, on which the supporting` or drive wheels 10' are mounted. One of the drive wheels is ,provided with gear teeth 11. An elongated Tcasing 12 is suspended from the arched portion of the aXle 8 by means of the straps 13, The front of the casing has an Opening 14, which is covered by the spitgation 0f gettare Patent Patented Sept. 11, 1911 *1.

`closure V15 hinged at 16. A curved partition 1T is mountedl Qn the interior of the casing 12 so as to divide ofi' a fan chamber 18. A

i shaft 19 is mounted in bearings of the cas ing, and on the shaft 19 a fan`20 is mounted to"`ro`ta`te withthe shaft'. The partition 17 is of a curvature to correspond with curvature of thev fan, and is providedA with a ucurved lip 21. A piece, of wire fabric 2,2 eX- Atends from the li'p 21 and is connected to the front wall Qfthe 12'. The rear wall ofthe casing`i12 at itsgupper portion has an Qpenino'23, which iscovered by `a piece of wire fabric 24. Depending down .A a l M i ii-'ardly frQm each end of the casing 12 are v auxiliary casings 25 having pneumatic passages 26. Connected at 27 to the two sides and therear 4wall of the lower end of each fiasng 25" iS a Saite-ble .fieXble skilt, niferably constructed Qf leather orthe'like. lt is tobe'noted that as the machine travels overtheield, the casings 25 pass over the rows of plants, said skirts, therefore, in this Cese, ride @ver the-tops ef therlailts and as the insects or boil" weevils"`have been shaken from the plants, the insects and the like are drawn upwardly through the passages 26, and over the lip 29 and into the poisonous solution 30, which is contained in the lower part of the casing 12. The fan 2O creates a suction in the passages 26, drawing the air through the screen 22 and forcing it out through the screened opening v23, the insects dropping into the poisonous solution. An arm 31 projects rearwardly from the lower part of one of the uprights of the aXle 8, and in a bearing of the free end of this arm, a stub shaft 32 is mounted, having the collars 33 to prevent axial movement of the stub shaft. One end of the stub shaft has a pinion 34 while `its, other end is provided with a sprocket 35, about which a chain 36 engages. On 'both ends of the shaft 19 are sprockets 37 and 3S, the sprocket 37 being engaged by the sprocket chain 36, while the sprocket 38 is engaged by a sprocket chain 39. One end of a shaft 40 is secured in a bearing 41 (which depends downwardly from the tongue 1) by means of the set bolt 42. The other end of the shaft 40 is mounted in a bearing 43 of the cross piece 44, which extends from one side of the frame to the other. Mounted to rock upon the shaft 40 are the sleeves 45, 46 and 47. The sleeve 46 is prevented from axial movement by the collars 48, which are iic wardly from the sleeve 46 are the` arinsi-S),V

posited"iitoltlre poisonous solution. By means of `the pinion 34 engaging the teeth which are disposed V-shapedrelative to each` 11, and jthroughfthe medium of the chains 35 other. Extending down from the sleeve 45 is an arm 51, and depending from the sleeve 47 isan arm 52. The arm 51 extends at an'f angle or an inclination corresponding to that of one of the arms49, while the arm 52 extends at an inclination corresponding to thatof the other arm 49.. A suitable plate 53 is connected to. one of the arms 49 and the arm51, while a second plate 541s conneoted to the other arm 49 and the arm 52, thereby providing a pair of agitator blades, which, through the vmedium of the sleeves 45, 46 and 47, are suspended from the shaft l 40, so as to be rocked. Extending upwardly 1:011164 f this gaten; maybe @manna for from the sleeve 46 is an arm 55, and mounted in bearings 56 of the bars 2 is a shaft 57. having a sprocket 58 at one end to be engaged `by the sprocket chain 39. Carried on and rotatable with the shaft 57 is a drum 59 provided with a cam groove 60, which receives the arm 55. This cam groove 60 is so constructed, that when theshaft 57 isrotated, the sleeve 45 will rock, and with it, the sleeves 46 and 47, thereby oscillating ,the agitator blades, which will come in 'contact with the top of the plants or the like,

'shaking them ysufficiently to cause the inl ,sects to fall therefrom and be drawn by the suction throughk the passages 26 and de- 36, motion is imparted to the shaft 19, which transfers motion to the shaft 57, which os-` "e'illates the agitator.

fThei'invention having been set forth, what isV claimed as new and useful, is

In an insect destroyer, a frame having an axle provided :with supporting wheels, a easing suspended on the` axle providedwith -a. receptacle 'for al poisonous. solution, said casing having atits ends downwardly depending pneumatic passages provided with fiexible skirts to drag over, the plantsand the like, a fan journaledin bearingsof the casing to create suctionsin said. passages, Vto g draw ,the insects -into the easing,means for deflecting the'insects into the solution, means of connection between the fanV and one `of the supporting drive wheels to impart motion to the fan, and ana'gitaton for shaking the insects Jfrom theplants, whereby they may Vbesucked into saidpassages.
